TOBACCO PIPE.

Application led October 16, 1919. Serial No. 330,974.

To all 'whom it may concern.'

Be it known that I, FREDRICK W. SMITH, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Tobacco Pipes; and I do hereby dec-lare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to tobacco pipes and has for its object to improve both the smoking action and the cleaning facility thereof. Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The improved pipe, in its preferred form, is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a vertical section taken axially through the pipe;

Fig. 2 is a section on lthe same line as Fig. 1, showing the stem removed from the bowl member; Y

Fig. 3 is an enlarged section on the line 3 3 of Fig. 1; and

Fig. 4 is a section on the same line as Fig. 3, but illustrating a different adjustment of the parts.

The tobacco bowl 5 is provided with a tubular shank 6 that forms a part of the complete stem of the pipe. The shank 6 is axial passage 7 which, at its inner end, is connected to the bottom of the interior of the bowl by a small port 8. A. long longitudinal channellike port 9 is formed in the passage 7 but exfrom end to end of the latter. Preferably, this long `port 9 is at the top of the shank. The numeral 10 indicates a metal ferrule. applied to the endV of the shank 6.

The stern proper, which is sometimes designated as the bit indicated by the numeral 11, is provided with an axially projecting stem extension 12 in the form of a metallic tube, one end of which is set into the stem 11 so that it is rigidly secured thereto. This stem extension 12 snuglyl fits the cylindrical passage 7 of the shank 6 and vis adapted to both slide and rotate therein lunder suiicient friction to prevent accidental rotations of thev stem in respect to the shank. At a point a considerable distance outward from its extreme inner end, the stem extension 12 is provided with a plug 13, and between its end and this plug, it is provided -w1th one or more, as shown, three radial orts 14. The end of the stem extension 12 1s filled with a porous filtering material( 15 preferably afforded by a small piece of sponge. In longitudinal alignment with the ports 14, the stem extension 12 ris provided with a port 16 located between the plug 13 and the stem 11, being quite close to the extreme inner portion of the latter. Stem 11 is further rovided with a small tubular extension 1 that is spaced concentrically within the cylindrical extension 12 and terminates short of the plug 13. The shank 6, at a point preferably ninety degrees from the radial plane of the long port 9, is provided with a so-called blow-oil' port 18, which, as shown, extends through the ferrule 10.

When the pipe is to be used, the stem or bit 11 is turned into the position shown in Figs. 1 and 3 and the line of travel will then be from the bowl 5 through port 8, thence through filtering material 15 and ports 14 into channel 9, thence through port 16 into the interior of the stem, extension 12, thence through tube 17, through stem 11. Moisture and the nicotine will be caught and held by the filtering material 15 so that only clean smoke, free Jfrom nicotine, will be delivered' to the mouth of the smoker. When the sponge or filtering material 15 becomes saturated, it may be replaced or may be quickly and easily cleaned, simply by removing and squeezing the same and replacin the same in position.

(fhe interior of the tubular stem extension 12, outward of the plug 13 affords a saliva chamber or trap for the collection of saliva, so that the pipe bowl will be kept dry. If at any time there is a considerable accumulation of the saliva in the saliva trap, it is only necessary to turn the stem so that the ports 14. will be closed andthe port 16 will be turned into registration with the blowoi port 18. When this is'done and air is blown through the stem 11, the only escape the aligned ports 16 and 18, and hence, the saliva trap or chamber can be cleaned out quickly at any time. Fig. 4 shows the stem turnedv into the blowo position just defor the saliva will be outward through in position for smoking. As the channel 12 'stem extension having a .smoking said extension is at the top, very little, if any, accumulation will be held in the said port. This pipe, therefore, is sanitary, will not quickly become clogged, and may be very quickly and easily cleaned.

What I claim is:

1. In a tobacco pipe, the combination with a bowl having a tubular shank, of a stem having' a -sleeve-like extension telescoped within said shank and rotatable therein, lsaid plug therein and peripheral ports normally disposed at the top thereof both with which the said ports are adaptedv to be aligned when the pipe is in' condition for closely iitting said shank peripherally, except at said channel.

2. In a tobacco pipe, the combination with y a bowl having a tubular shank, of a stem having a sleeve-like extension telescoped within said shank and rotatable therein, `said stem extension havin a plug and peripheral ports b'oth inwar and outward thereof, said shank closely fitting said extension peripherally, except for a small internal channel at the top thereof with which the ports of said extension are adapted .to be aligned when the and a filtering material in the inner end of said stem extension through which the smoke must be passed to the inner ports of-said stem extension.

3. In a tobacco pipe, the combination with a bowl having a tubular shank, of a'stem having a sleeve-like extension telescoped within said shank and rotatable therein,.said

stem extension having a plug and peripheral ports both inward and outward thereof, said shank having an internal channel with which the ports o'f said extension are adapted to inward and outward. thereof, said shank having an internal channel extending along the top of said extension lshank. of said bowl having out of line withthe internal yaligr'i fthe outer port fjwith: said blowoff port.

pipe is in condition for smoking,

a bowl having a tubular shank, of a stem lhaving a sleeve-like extension telescoped vwithin said shank and rotatable therein, said stem extension having a plug and peripheral ports both inward and outward thereof, said-shank having an internal channel' with-.which'the ports of said extension lare-adaptedt'o loe-aligned when the pipe is -in'conditionfor smoking, a filtering material inthe .iniierjend` cf said stem extending through which the smoke must be passed to the inner portsof said stem extension, the 'a blow-ofi' port channel thereof, and'saidjstem being rotatable to close the linnerfp'ortsffofsaid stem extension and to of said stem extensionl 5, In atiobacco pipe provided with a bowl havinga tubular shank, a stem having a sleeve-like extension telescoped within said shank and rotatable therein, said extension closely fitting said shank except for a small channel extending along the top thereof, a plug in saidy extension and peripheral ports at the top' of said extension both inward and outward of said plug communicating with' said channel, said stem having the usual longitudinal aperture therethrough, and a tube projecting from the inner end thereof into said extension but terminating short of said plug.

In testimony whereof I aiiix my signa- 8 ture , FREDRICK W. SMITH.
